So what about this chip? Let's have a look.~

Integrated 5G, 103 billion transistors

Kirin 9905G, 7nm EUV process, using the fully integrated 5G chip design, the area is smaller, the board level area is reduced by 36%.

The area has decreased, but the number of transistors has not decreased.

Yu Chengdong said that Kirin 9905G, is the industry's first mobile terminal chip with more than 10.3 billion transistors, using EUV manufacturing process, the number of 10.3 billion.

By contrast, the number of transistors in Kirin 980 is 6.9 billion, up nearly 50%.

In terms of speed, Kirin 9905G has the highest downlink rate of 2.3 Gbpss and the highest uplink rate of 1.25Gbps.

For the 8nm chip Exynos 980 released by Samsung, it is implemented.

He said that based on the 3GPP R-15 protocol standard, the theoretical rate of 100 MHz bandwidth can be achieved up to 2.34 Gbps, which can break through, are non-standard.

data-croporisrc=https://mmbiz.qlogo.cn/mmbiz_png/YicUhk5aAGtDEzr0LibN5OTFD9VMOUgqibPuicWuFuQ6ial72xX9LAibuDsbYBGaBH6Xia2vGnj2GN14YvGKXO7FH7Tlg/0?wx_fmt=png

Yu Chengdong said that while achieving high speed, the chip can also achieve the best energy efficiency in the industry, compared with the traditional 4G SoC 5G Modem solution, the energy efficiency is improved by 20 percent. Under light load data, the power consumption can be reduced by 44%.

Just last month, IHS, a foreign research firm, released a report saying Huawei's 4G SoC 5G Modem solution wasted energy efficiency, and now the release of Kirin 9905G is no doubt in response to that challenge.

Similarly, Kirin 9905G is the industry's first all-netcom 5G SoC, which takes the lead in supporting SA/NSA dual architecture synchronously and TDD/FDD full-band.

However, it is still in the early stage of 5G business, and the network coverage is not perfect, the most direct embodiment is to fall back to 4G in the environment of high-speed movement and weak signal.

data-ratio=0.5328125

In these cases, Huawei also offers solutions.

Firstly, the adaptive receiver based on machine learning is supported, the optimal network is automatically selected according to the strength of 5G signal, and the stable 5G connection is realized, so that the downlink rate is increased by 19%.

Intelligent upstream shunt design is adopted for upstream network, which can be used in video live broadcast, short video upload and other application scenarios.Using 5G and 4G networks at the same timeUpload rate increased by 5.8 times.

However, the ability of this chip is not limited to 5G, but the performance and AI are greatly improved. The most intuitive feeling is the image processing ability.

Apply image denoising technology of SLR to mobile phone

Kirin 9905G adopts ISP 5.0, the main optimization is video processing ability, the data has been greatly improved: ISP throughput increased by 15%, energy efficiency by 15%, photo noise reduction by 30%, video noise reduction by 20%.

On the basis of ISP capability upgrade, Kirin 9905G AR capability has been upgraded again.

Yu Chengdong said that the face image data captured from the camera and the neural network algorithm, Face AR based on NPU can not only model the face, track the face in real time, capture the expression, but also further analyze the health data such as heart rate and respiratory rate.

data-ratio=0.5477707006369427

Huawei has also devoted a lot of attention to video and image denoising.

Yu Chengdong said: Kirin 9905G implements dual domain video noise reduction technology on mobile phone chip for the first time. Aiming at the mixed scene of high frequency, intermediate frequency and low frequency noise in video, the noise reduction process in frequency domain is increased, with emphasis on accurate separation of noise, and the video captured in dark light environment is clearer.

data-ratio=0.35753176043557167

Moreover, it is the first time to implement real-time video post-processing rendering technology based on AI segmentation on mobile chip.

In image processing, BM3D (Block-Matching and 3D filtering) SLR hardware noise reduction technology is implemented. This is also the first time that SLR image processing power has been applied to mobile phones, with less noise in dark light scenes.

Not only the chip design and process, but also the AI and performance behind Kirin 99005G.

AI points hit a new high, the industry's strongest AI calculation powe

On NPU, Huawei has adopted a new design: the design of the two core microcores, which inherits the Shengteng series of chips for smartphone scenarios.

The big nucleus in Kirin 9905G is Ascend Lite. Yu Chengdong said that based on this, Kirin 9905G achieves the strongest AI computing power in the industry.

Microcore, or Ascend Tiny, is mainly used for ultra-low-power applications, and in the face recognition application scenario, the NPU microcore can increase the energy efficiency by up to 24 times and save more electricity than the large core.

Huawei also uses it.

The original nuclear, no matter how many goods need to use.

For Kirin 9905G AI performance, Yu Chengdong gave a running score: compared with Kirin 970, it increased 12 times, reached 76206 points, and was three times as much as Friends.

This running point comes from the AI Benchmark, proposed by the University of Zurich, which has become an important benchmark for the industry to run points, and is also a direct embodiment of AI ability.

Ai Wei also explained why he was able to achieve such a big promotion: he used the Da Vinci framework developed by Huawei.

data-ratio=0.67109375

Specifically, the 3D Cube, used in Leonardo da Vinci architecture can accelerate the matrix operation and greatly improve the AI computing power per unit power consumption.

Each AI Core can implement 4096 MAC operations in one clock cycle, which is an order of magnitude improvement over the traditional CPU and GPU.

Yu Chengdong said that the performance of Kirin 9905G is not only reflected in running points, but also has very strong performance and energy efficiency in the running model, such as in Mobilenet,Resnet and other models, compared with competitors, the performance is as high as 6 times and the energy efficiency is as high as 8 times.

data-cropselx1=0

The number of operators has also reached 300, supporting 90% visual computing neural networks, such as VGG Resnet Mobilenet and so on.

Yu Chengdong said Kirin 9905G also made many applications possible because of power consumption and limited computing power, and demonstrated them on the spot.AI multi-person real-time background changeAn example.

Based on AI multi-instance segmentation technology, each character subject in the video picture can be identified separately, and the multi-character video shooting can replace the background. Similarly, it can also make the other people in the video disappear.

Performance: 8 core CPU 16 core GPU

After that, Yu Chengdong gave the basic performance data of Kirin 9905G as a SoC chip:

Kirin 9905G adopts two super large cores (based on Cortex-A76) and two large cores (based on Cortex-A76) and four small cores (Cortex-A55) architecture.

The maximum main frequency can reach 2.86 GHz, which is 10% higher for single core and 9% higher for multi-core than that of Yuelong 855.

data-ratio=0.3993089832181639

In terms of energy efficiency, the efficiency of large nuclear energy, medium nuclear energy and small nuclear energy is 12%, 35% and 15%, respectively.

As for GPU, Kirin 9905G has been upgraded to 16-core Mali-G76 GPU. Compared with Qilong 855, the performance of graphics processing is 6% higher and the energy efficiency is 20%.

data-ratio=0.38215962441314555

Yu Chengdong also joked about the next friends, said they released the PPT 5G module, also used the 5 core GPU.

Similarly, Huawei has optimized the game.

data-ratio=0.36531365313653136

Not only is there Kirin Gaming 2.0, but there is also a system-level SmartCache shunt, which supports intelligent allocation of DDR data, and the bandwidth can be saved up to 15% and the power consumption can be reduced by 12% compared to the previous generation in large bandwidth scenarios such as heavy-haul games.

AI FM scheduling technology has been upgraded again. For the first time, GPU FM scheduling has been integrated into CPU and DDR FM scheduling system to realize intelligent integration scheduling of CPU/GPU/DDR. The accuracy of load FM per frame of the game has been improved by XX%, and the frame rate of the game has been stabilized by 60 frames.

Huawei Mate 30 Conjecture

Huawei has a consistent rhythm, after the release of chips, mobile phones will also appear.

Take the lead in the Qilin 9905G chip, which is the same as the Mate 30 series that was released in Germany in this month.

So what breakthroughs and performance improvements will the Mate 30 series make with Kirin 9905G?

data-ratio=0.43297380585516176

Combined with the latest revelations, we might as well make a summary and conjecture:

First of all, Kirin 9905G adopts the integrated 5G design instead of 4G SoC 5G module. The board level area is smaller and the energy consumption is smaller. That means Huawei can have bigger batteries and longer battery life than other 5G phones.

Secondly, both ISP and AI image processing capabilities have been greatly improved. With the improvement of camera parameters revealed by Huawei, new capabilities will emerge in both photography and image processing.

At this press conference, also revealed some new capabilities. For example, AR can not only track the face, but also measure the heart rate.

As well as AI multi-instance segmentation technology, it can segment multiple people. It also has similar functions on Mate 20, but at that time it can only recognize single people.

And the unicorn 990, it should be possible to let the mobile phone realize the real-time video p-person.

Third, play games. Glory 9X, which carries Kirin 810, claims that mainstream hand-swimming is full of frames. This time, using Kirin 9905G Mate 30 series, it will certainly be stronger.

Fourth, the price. Huawei has worked hard to integrate 5G into the chip this time, and the 5G phone is still in its early stages of development, the cost is not low, the price is inevitable, but according to Huawei's custom, the domestic should also be cheaper than elsewhere.

Finally, Yu said Kirin 990 has 5G and non-5G versions.

Except for the integration of 5G, the performance comparison data are as follows:

data-cropselx1=0

This also indicates that there may be two versions of the Mate30 series: with 5G and without 5G.

I do not know if there is 5G, Huawei's price difference will be how much?

How much price difference can you accept? 500 yuan? 1000 yuan? Or will it buy 5G no matter how bad it is?
